【 Weak current College 】 sound effects of unsatisfactory 10 main causes and solutions

10 reasons: some of the major events of the responsible person does not know what is the best acoustics, must spend much, don't know how to request.
For a long time they do a lot of little success, however, they do not know this situation is worse. For example, a background music, lectures, dance, etc., of the spectator with 450 events, should use the large sound reinforcement system, they often employ a simple mixer DJ. They lower the price, a penny more reluctant. Unfortunately, some of these guys really know how to get good results you must be willing to invest, but they scoff.
Solution is not very easy. But the first thing to know is, dealing with such issues is the most professional way, once the situation is a foregone conclusion, but the best you can do your best work. The downside is that if you succeed, then it will also continue (of course, if you fail, is likely to blame). Therefore the author of the first recommendation is to directly deny those similar party a party b, and politely explained that you and your company's goal is to party a to provide professional sound services, only so little money it is not possible to provide professional equipment and personnel to achieve the desired result.
If the first method is not successful (usually unsuccessful — because when we are aware of the results is awful when it is too late), the next step is after the end of the concert very politely tell the Organizer, if they invest more money and heard the right professional recommendations, many problems can be avoided, it can get better sound effects (meaning customers more and more satisfied). They may not be willing to listen to, but at least you should avoid as they work, and you also can warn you of friendly competitors do not take over the project.
Cause 9: poor acoustic conditions.
Some sites are indeed very difficult to achieve an ideal acoustics. Albuquerque city have a Tingley Coliseum, many bands in concert, held in this city one ofthe reasons is the establishment of sound effects. But to a certain extent, can still be improved. I've seen a field effect is good, show just the Tingley Coliseum organized Canada singer SarahMclachlan concerts. She is also the tuner recognizes the venue is GaryStokes suboptimal, but he has taken numerous measures. He said: "If BarbaraStreisand concerts, we can put more money and had to hang up the thick curtains to the back one-third of the space separated ..." in other words, he was well aware of the need to do to get better sound effect.
Room acoustic conditions in question cannot be used to increase the volume of the sound amplifying equipment to solve, you should think about how sound walls, ceilings, etc. to avoid, the sound must and can only reach the audience and not elsewhere. Try to reduce the volume on the stage, using personal listener is a good way. You can't complain "this side of the room was really bad." Side as usual work and not to take any necessary measures.
Cause: not enough devices 8.
Sometimes this causes the first ten reasons, but usually this difficulty can be overcome. If sound amplifying equipment cannot cover the entire site, so you can find several speakers or resize the speaker setup to get the best results. Once in a three-storey blocks of theater, local staff said that the existing sound amplifying equipment cannot overwrite the third floor gallery, he tuned speaker set-up, allowing the underlying and third floor gallery is a very good sound effects, it is reasonable compensation measures; and then in existing sound amplifying equipment adds some additional alignment layer 3 treble speaker of the dress circle, and achieved the desired result.
Reason 7: stage volume is too large.
Nearly 20 years, with personal listening devices are widely used, this problem can be solved. But as singer, performed by budget or have not yet mastered personal listening system using methods for various reasons, many tours, events and performances still use za. So when za, drums, guitar and other equipment on stage through all the microphone into the mixer, mixer may overload.
I strongly recommend that, if you have used personal listening system, understanding the nuances of using effects, and then look for other methods of weakening stage volume. Guitar Player is not a Guitar Cabinet at the back of his knees? drummer with enclosures? are there any other ways you can reduce the microphone picks up sound of "Wash"? in these details and make more, can be more clear voice, and also to better control the sound effects.
Reason 6: sound delay.
Since people use a mixer of digital delay, audio processors and other equipment, there is no reason to ignore the delay problem. If on the stage, platform, platform or wherever the pendulum one on either side of the bracket speaker, and if the delayed signal method is not appropriate, to the viewer feeling is the sound from the speakers, not from the speaker or the singer. To learn more about the speed of sound (at room temperature, atmospheric pressure of one standard 1130ft/s). Know that in mind, consider how to delay the signal, making the most of the audience to hear the voice of the speaker's voice than the sound source is a little bit earlier. According to Haas effect this illusion will make you feel the sound is coming from people not from sound amplifying equipment.
Reason 5: improper use of the wireless microphone.
Due to the design and the expected results, leading wireless microphone work status as "witchcraft" and, therefore, some people will say "I do". But the reality is almost always possible measures, should be treated with scientific methods, the physical principle is in effect. But if you use the poor quality of wireless microphone, and achieved good results of like playing with Chinese or Russian-roulette gambling as low. But as long as you can on each channel to spend $ 400 or more money, the rest is just antenna design and frequencyselection. Carefully read the device's user manual to obtain such famous manufacturers provideProduct information. On the wireless device more useful to know the absolute is also familiar with frequency innocuous regulating the use of software.
Reason 4: hearing loss.
If the mixed sound too strongly, operators are likely to lose their hearing. Therefore, it is strongly recommended each year for a hearing check. If hearing impaired, and consider changing it. If you continue to do the work, will further mixing damage hearing and your mixer effect will become more and more worse.
Reason 3: trolley, terminal equipment and grounding techniques.
Sometimes a small shield line can cause heat short-circuit or ground loop connection. Should be made for the microphone cable for regular maintenance, to take appropriate measures to check and clean the plug device, grasp the earthing and grounding circuit of knowledge. Finally, line impedance and level also needs to master. Also learn when to use DI input; why 300 Ω guitar microphone plugs into 1 k Ω microphone socket is wrong.
Reason 2: gain structure.
This issue should not be overlooked. We often have reflected sound system is good, at least 70% and gain structure. The main problem is the fore gain insufficient level gain increased after the circuit, the result is too much noise, strength is not enough; the second most common reason is that bus overload, because all the energy channels are great, when it comes to afford greater than 28dBu bus amplifier, the sound is being squeezed much distortion, displeasure. And the old recording and a lot to analog tape imbued signal, to the channel and bus input too much signal is not very desirable, so long as it can get the most out of signal to noise ratio is fine, not too much resulting in the sound appears obvious distortion.
Cause 1: mixing skills lacking.
Skills lacking many features, but the most common is the volume is too big, too loud, too distorted, integrated as a result, the definition is not high. The device is not good and not a very good excuse, I have on many occasions see the same set of sound amplifying equipment by different people to action, A operation sounds terribly: bass, low turbidity, baritone messy extension, treble sound distortion, musical instrument, a drum with a mixture of inundation is too large, especially in the drum, vocal intruding; B operation results in unexpectedly good: clean extension of the bass, the musical instrument sound legible, not low-frequency noise, voice pleasing clear treble beautiful and it opens up.
The main difference is that the operator. Of course the platform players also have a different part of the reason, but the stage equipment basic is the same – drums, bass, guitar, keyboard, and the human voice. The true variance is the person behind the mixing console, a know what to do, another is not clear.
What to do next?
How to improve mixing skills? first, lay down their shelves, with an open mind. Sound mixing styles of each individual is different, but good mix masters have in common, know what you want, know how to achieve such an effect. They heard the sound always critical, and objective. They know, whether it be for drum pickup or guitar using the equalizer, rushing brutal way. Their work is always first to understand all the musical instruments and how the coordination between the human voice, and then find a feasible solution, let every voice can appear.
Outstanding sound mixing engineers thinking and open, Active Discovery issues and take action. They know that the performers want what the audience expects. These are the skills can be learned.
